Nice teardown. I have been hoping to find a diagram to see how the gear systems interact. My unit picks paper and pushes it to the rear rollers but the rollers are not turning. They spin freely and I think that is odd unless there is a clutch or a broken gear. Hence my looking for a diagram. Do you know how these rollers are fed? Do they have their own motor??
